If AE is x+50 then the whole thing must be x=50, If a portion of that, CE, is x+32, then the rest of it, AC, must be x+18, because no matter what X is, 32+18=50.

There are several factors that influence how each of us consumes energy. It is close to impossible to ask every person in the world, every family or even all countries to consume a specific amount of energy per day just for us to measure if everyone received an equal share. For me, energy consumption is evenly distributed if the supply meets the demand. So long as no country is suffering from darkness or there is no household without electricity, then energy is properly distributed.
